Question 12 Consider the titration of 50.0 mL of 0.350 M NH3 (K, = 1.74x10 5) with 100 mM HCI. What will the pH be after 0.500 equivalents of HCl are added? Provide your answer to two decimal places. Question 13 Consider the titration of 1.000 L of 0.100 M HA (pKa = 6.11) with 0.169 M NaOH. What volume of NaOH must be added to reach pH = 6.61? Provide your answer in milliliters (with the allowed 3 significant figures) but do not give the units.

What is the pH of a buffer prepared by adding 0.506 mol of the weak acid HA to 0.305 mol of NaA in 2.00 L of solution? The dissociation constant Ka of HA is 5.66 × 10-7. Express the pH numerically to three decimal places. • View Available Hint(s) pH : = 6.027 Submit Previous Answers Correct Important: If you use this answer in later parts, use the full unrounded value in your calculations. Since both the acid and base exist in the same volume, we can skip the concentration calculations and use the number of moles in the Henderson-Hasselbalch equation to calculate the pH. The answer will be the same. Part B What is the pH after 0.150 mol of HCl is added to the buffer from Part A? Assume no volume change on the addition of the acid.
